  • Niello - A compound made up of lead silver copper and sulphur that is black in colour, and applied to the engraved areas of silver items, thus highlighting the engraving by making the black niello detail stand out from the silver background. It was used on edged weapons from the Renaisance onwards, and also by Russian crafstmen of the19th century.
  • George Ii - George II (1683 - 1760) was King of Great Britain and Ireland from 1727 until his death in 1760.
  • Fusee - The fusee movement was used in clocks and pocket watches from the mid 17th century. The fusee is a cone shaped drum within the works that is linked to the barrel of the spring, usually by a length of chain.

    As the mainspring loses its tension over time, the cone shaped barrel compensates for this by increasing the tension, by pulling the mainspring tighter, thus ensuring the time remains constant.

    Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.

    The fusee continued to be used in marine chronometers until the 1970s.
  • Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
